3-K FOR ALL After an historic expansion of pre-K for 4-year-olds, Mayor Bill de Blasio announced on Monday that the city wants to enroll all 3-year-olds in free pre-K by 2021.

Opinion: The mayor’s plan to extend pre-K to 3-year-olds, starting first in needy districts, doesn’t address poor performance of schools in those districts. New York Post

Opinion: Requiring huge outside investment, de Blasio’s plan to make pre-K universal for 3-year-olds is akin to a businessman “announcing a massive expansion with no clear idea of where his financing is coming from.” New York Post

Opinion: Pre-K is an investment that can have a “profound impact” on children and yield economic benefits, says Shael Polakow-Suransky, President of Bank Street College of Education. New York Daily News

Opinion: Expanding pre-K to 3-year-olds is a smart move for children — and for de Blasio’s reelection bid. New York Daily News
